Marijuana exerts its psychological effects through the actions of its active ingredient THC. What is the mechanism of action of THC? A. THC blocks dopamine reuptake transporters in the nucleus accumbens B. Marijuana does not act on the brain C. THC binds to receptors on dopaminergic terminal buttons in the nucleus accumbens to increase dopamine release D. THC binds to receptors on GABA neurons in the ventral tegmental area to increase dopamine activity
A patient comes into a hospital emergency room sedated and non-responsive. She had been at a college party where she drank many shots of vodka. What is the most likely explanation for her behavioral and physiological symptoms? A. The alcohol increased the actions of GABA at the GABA receptor chloride channel B. The alochol increased dopamine and serotonin activity by running the transporters backwards C. The alcohol blocked the dopamine reuptake transporter D. the alcohol activated serotinin autoreceptors in the brain E. none of the above
What is the most likely mechanism producing tolerance to cocaine and then the dysphoria that is associated with cocaine withdrawal? A. Dynorphin neurons cause presynaptic inhibition to decrease dopamine release into the nucleus accumbens B. Cocaine runs the dopamine transporter backwards to cause tolerance and withdrawal C. cocaine binds to opiate receptors in the ventral tegmental area (VTA) D. Dynorphin neurons stimulate dopamine neurons in the ventral tegmental area (VTA) and increase dopamine release into the nucleus accumbens

Neurotransmitters: a. Can only inhibit the postsynaptic cell b. Can be part of a process that regulates transcription and translation in the postsynaptic cell с. Are bound to their receptors forever, until the receptor is degraded and recycled. d. Can exit the presynaptic cell without assistance. e. Can only excite the postsynaptic cell Clathrin: Is embedded in the cell membrane of the synaptic terminal. a. b. Degrades vesicles for recycling and return to the axon hillock с. Mediates ALL endocytosis in the body, including the formation of vesicles in the synapse. d. Forms a coat of octagonal proteins. e. Helps the vesicle leave the pre-synaptic cell, and fuse to the membrane of the post-synaptic cell
Cocaine addiction occurs whena. cocaine binds to dopamine transporter proteins on the presynaptic membrane.b. the numbers of postsynaptic dopamine receptors are reduced in limbic system nerve cells. c. neurotransmitter levels rise in lymbic system synapses.d. dopamine transporters become disabled.

If a cell were to express both alpha-1 and beta adrenergic receptors what would the expected response to epinephrine/ adrenaline be ? a. Only cAMP would be released b. Both ca2+ and cAMP would be released c. The receptors would cancel each other and nothing would happen d. Only ca2+ would be released would be released.
A neurotransmitter called "GABA" decreases the rate of action potential generation in neurons, but the effect can be overridden by excitatory neurotransmitters. Alcohol binds to the GABA receptor and has the same effect. Alcohol must Select one: a. Cause depolarization in neurons b. Cause hyperpolarization in neurons c. Block calcium entry at the axon terminus d. Block voltage-gated sodium channels
